The patch titled
GRU driver: driver/misc Makefile & Kconfig changes
has been removed from the -mm tree. Its filename was
gru-driver-v2-driver-misc-makefile-kconfig-changes.patch
This patch was dropped because it needs mmu notifiers, which I don't have
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

+ The GRU is a hardware resource located in the system chipset. The GRU
+ contains memory that can be mmapped into the user address space. This memory is
+ used to communicate with the GRU to perform functions such as load/store,
+ scatter/gather, bcopy, AMOs, etc. The GRU is directly accessed by user
+ instructions using user virtual addresses. GRU instructions (ex., bcopy) use
+ user virtual addresses for operands.
